I have a 9004 managed by central.
Interface 0&1 goto lan through port channel 1, 2 & 3 goto wan links.
I did some work on the port channel and vlans for the LAN side; then I noticed that my WAN link, port 3 is beling identified as a LAN link in central's "network overview".
All my WAN configs appear correct.
In the config, the interfaces and vlans are nearly identical.
The WAN tag is still applied to the interface
What makes central define a link as WAN or LAN ?
